IABP
An investigation was undertaken to determine whether the blood supply through narrowed coronary arteries could be improved by delaying the arterial pressure wave so that it arrives in the coronary arteries during diastole.
In 1967 it was clinical introduction.
Currently 100.000 implantation per year.

CONCLUSIONS
The use of intraaortic balloon counterpulsation did not significantly reduce 30-day mortality in nupatients with cardiogenic shock complicating acute myocardial infarction for whom an early revascularization strategy was planned. (Funded by the
German Research Foundation and others; IABP-SHOCK II ClinicalTrials.gov mber, NCT00491036.)

Extra Corporeal Membrane Oxygenation
(ECMO)
•
A form of extracorporeal life support where an external artificial circuit carries venous blood from the patient to an oxygenator where blood becomes enriched with oxygen and has carbon dioxide removed.

ECMO
•
The blood is than returned to the patient via a central vein or an artery.

Impella
The smallest heart pump in the world
9 Fr catheter, 12 Fr / 14Fr microaxial
Produces 2.5 / -4 L / min forward flow
Increases:
coronary flow
the systemic flow
cardiac output which is in direct correlation to mortality
Abbas Ferdosi M.D.

Impella
Discharges directly to the Ventricle:
The pump pumps the blood from the LV
Resulting in a reduction of the wall voltage
Reduction of O 2 demand in the myocardium
While at the same time increases the O 2 supply
Regardless of the heart rhythm and catecholamines

Impella Controller (AIC) for monitoring and control of the Impella pump and the purge system.

Promotion of blood
The rotating drive sucks blood through the cannula
Impella controller (AIC) controls the rotation speed of the drive
The rotational speed is proportional to the flow
Faster rotation = Higher flow

A prospective, randomized clinical trial of hemodynamic support with
Impella 2.5 versus intra-aortic balloon pump in patients undergoing high-risk percutaneous coronary intervention: the PROTECT II study.

J, Douglas PS, Ohman M.
CONCLUSIONS:
The 30-day incidence of major adverse events was not different for patients with
IABP or Impella 2.5 hemodynamic support. However, trends for improved outcomes were observed for Impella 2.5-supported patients at 90 days.
